NOTE:
NISSAN does not advocate the se of non-
OEM approved af termarket flushing sys-
tems and strongly advises against per-
forming these services on NISSAN
products. Many of the af termarket flush-
ing systems use non-OEM approved
chemicals or solvents, the use of which
has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capaci-
ties” (P. 10-2)
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belt*:Check engine drive belt for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belt.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
Engine coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-4).
NOTE: Mixing any other type of coolant
or the use of non-distilled water may re-
duce the recommended service interval
of the coolant.
Engine oil and oil filter:
Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
Engine valve clearance*: Inspect only if
valve noise increases. Adjust valve clear-
ance if necessary.
Evaporative emissions control vapor
lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel filter: Periodic maintenance is not re-
quired. (in-tank type filter)
Fuel lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the type as originally
equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or dam-
aged parts immediately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
In-cabin microfilter: Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Steering gear and linkage, axle and sus-
pension parts, drive shaf t boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire rotation: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
9-6Maintenance and schedules

• Exhaust system
• Steering gear & linkage
• Axle & suspension parts
• Front drive shaf t boots
(1) Performed based on the number of
miles only
(2) Replace spark plug when the plug gap
exceeds 0.053 in (1.35 mm) even if within
specified periodic replacement mileage.
(3) First replacement interval is 105,000
miles (168,000 km) or 84 months. Af ter first
replacement, replace every 75,000 miles
(120,000 km) or 60 months.
"Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% antifreeze
and 50% demineralized or distilled water.
Mixing any other type of coolant or the use
of non-distilled water may reduce the life
expectancy of the factory fill coolant.”
